Great use of super here! Consider removing the category from the constructor arguments on line 3. We know we always want it to be "Clothing" so we don't want to allow changing it when instantiating an instance.

Tiny style point here and elsewhere: when defining default arguments don't include spaces on either side of the equals sign. We would instead write it like:
def __init__(self, category="Electronics", condition=0):
| if self.condition == 0: | ||
| return "Poor" | ||
| if self.condition == 1: | ||
| return "Fair" | ||
| if self.condition == 2: | ||
| return "Good" | ||
| if self.condition == 3: | ||
| return "Very good" | ||
| if self.condition == 4: | ||
| return "Like new" | ||
| if self.condition ==5: | ||
| return "New" |

Great job having this be defined here once and inherited by the child classes!
| '''Adds an item to a vendor's inventory''' | ||
| self.inventory.append(item) | ||
| return item |
| if not inventory: | ||

| self.inventory = inventory |

Nice job avoiding a mutable default object.
| "Returns a list of items of a category in a vendor's inventory" | ||
| item_list = [item for item in self.inventory if item.category == category] | ||
| return item_list |
| '''Swaps the first item in two vendor inventories (self and vendor)''' | ||
| if self.inventory and vendor.inventory: | ||
| return self.swap_items(vendor, self.inventory[0], vendor.inventory[0]) |

Love how you re-use your earlier method! One small bug here: according to the README this method should return False if either of the inventories is empty, but it actually returns None.
| '''Returns the best item in vendor inventory by category. If multiple items, returns the item with the highest condition''' | ||
| items_list = self.get_by_category(category) | ||
| if not items_list: | ||
| return None | ||
| best_item = items_list[0] | ||
| for item in items_list: | ||
| if item.condition > best_item.condition: | ||
| best_item = item | ||
| return best_item |

Great logic and re-use of method here!
| assert result == "c" | ||
| assert vendor.inventory == ["a", "b"] |
| # - That the results is truthy | ||
| assert not result |
